I recently upgraded my OS to Ubuntu 14.04 LTS. Everything was fine until now, whenever I try to update or install software via terminal I get this message:

E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

I have no idea what other process could be running on background . Please help I am not enjoying my new O.S. Thanks.

Run sudo rm /var/lib/dpkg/lock in terminal which will remove the lock file created by any of the dpkg applications(like synaptic, ubuntu-software-center etc.). Then do sudo apt-get update.
